+# Circleback
+
+Cursor plugin that connects agents to [Circleback](https://circleback.ai) through Circleback's official remote [Model Context Protocol](https://modelcontextprotocol.io/) server.
+
+Search meetings, transcripts, action items, calendar events, and emails, and look up people and companies in the signed-in Circleback account.
+
+## Install
+
+1. Open **Cursor Settings → Plugins**.
+2. Search for **Circleback**.
+3. Click **Install**, then complete the Circleback sign-in prompt.
+
+Or run `/add-plugin circleback` in chat.
+
+## MCP
+
+```json
+{
+  "mcpServers": {
+    "circleback": {
+      "type": "http",
+      "url": "https://circleback.ai/api/mcp"
+    }
+  }
+}
+```
+
+Auth is OAuth 2.0 against Circleback with Dynamic Client Registration (DCR) and PKCE. Cursor registers itself and prompts for Circleback sign-in when the plugin connects — there is no API key or client ID to configure.
+
+## Notes
+
+- Tool calls run as the Circleback user who authorizes the connection and cannot exceed that user's permissions.
+- Agents can search meetings and transcripts, pull notes and action items, search calendar and email, and look up people or companies tied to your Circleback history.
+
+## Docs
+
+- Circleback MCP: https://support.circleback.ai/en/articles/13249081-circleback-mcp
+- Server URL: https://circleback.ai/api/mcp
+
+Logo is Circleback's official apple-touch icon from https://circleback.ai/apple-touch-icon.png.
